SPECIFICATION formingpart of Letters Patent No. 232,727,

dated September 28, 1880,

Application filed August 18, 1880. (No model.)

To all whom it may concern:

Be it known that we, Tnonas KEITH and ANDREW PHILP, of the city, county, and State of New York, have invented a new and Improved Hand-Stamp, of which the following is a specification.

The object of our invention is to provide a new and improved self-inking hand-stamp 'vhich is simple in construction and effective in use.

The invention consists of a die-plate guided by vertical slots in the standards of the frame of the stamp, and pivoted to arms rigidly attached to a transverse bar attached to the handle, which die-plate has a fork on the lower side, embracing a stud or pin attached to a rod provided with a symmetrically-beveled guide-plate, and fitting into a receptacle containing a spring, which forces the guide-plate forward against the gudgeon of the die.

In the accompanying drawings, Figure 1 is a front elevation of ourimproved hand-stamp, and Fig. 2 is a cross-sectional elevation of the same on line no as, Fig. 1.

Similar letters of reference indicate corresponding parts.

The die-plate A is pivoted to the arms B B, rigidly attached to the transverse bar G of the handle D, and the gudgeons E E of the die-plate pass through the vertical slots F F in the standards Gr G of the stamp-frame. The handle D is hollow to receive the guiderod H,and contains a spiral spring, J, to force it upward when relieved.

The handle may be locked in any desired position in relation to the guide by means of the binding-screw I The die-plate A is provided with a fork, K, on the under side, which fork embraces a pin, L, attached to the outer end of a rod, M, fitting into a tubular or like receptacle, N, soldered, riveted, or cast to the frame of the stamp, and containing a spiral spring, 0, which forces the rod M outward. A guide-plate, P, which is symmetrically beveled backward from the pin L, is attached to the forward end of the rod M, the said rod M, plate P, and pin L being integral or soldered or welded together.

The operation is as follows: As shown, the face of the die rests against the ink-cushion M. If the handle D is now depressed, the

gudgeon E of the (lie-plate presses upon the upper outward edge of the guide-plate P, and consequently forces it out of the way, and as this guide-plate is attached to the rod M it will move in the direction of the arrow a but if the plate P and rod M move in this direction the pin L must do so likewise, and the lower end of the fork K is drawn in the same directionthat is, the dieplate A is turned over in the direction of the arrow l), for the farther the gudgeon E descends the more the pin L will be drawn in the direction of the arrow (0. When the die-plate A is vertical the gudgeon E will have reached the apex of the plate P, which will now begin to move back in the reverse direction of the arrow to, and as the die-plate descends it will be completely turned over, so that its inked surface prints on the paper. As soon as the handle is released the spring J throws it upward, and thereby raises the die, which performs the same movements as described, but in the reverse order, and the guide-plate P is thrown back into its normal position by the spring 0 acting upon the arm M.

Having thus described our invention, we

claim as new and desire to secure by Letters Patent- 1. In a hand-stamp, the combination, with the gudgeon E of the die-plate and the fork K, secured to the under side of the said plate, of the sliding symmetrically-beveled guideplate P, provided with pin L, substantially as herein shown and described, and for the purpose set forth.

2. In a hand-stamp, the combination, with the dieplate A, of the fork K, pin L, symmetrically-beveled guideplate P, rod M, and spring 0, substantially as herein shown and described, and for the purpose set forth.

3. In a hand-stamp, the combination, with the die-plate A, of the fork K, pinL, guide-plate P, rod M, spring 0, gudgeons E E, arms B, transverse bar 0, handle D, and slotted standards G G, substantially as herein shown and described, and for the purposes set forth.
